HENRY N. DEGRAW, OF IVATERVLIET, NEW YORK.

To all whom 'it may concern;

MACHINE FOR WASHING BOTTLES.

Be it known that I, HENRY N. DEGRAw, of Watervleit, in the county ofAlbany and State of New York, have invented a new` and ImprovedImplement or -Device for Washing Bottles; and' I do hereby declare 'thatthe following is a full, clear, and eXact description of the same,reference being had *to the annexed drawings, making a part of thisspecification, in which- Figure l. is a longitudinal vertical sectionpassing through the center. Fig. 2. is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in thefigures.-

My invention consists in the employment or use of a rotating andexpanding brush used in connection with a sliding holder, the

parts being so arranged as will be herein' after fully shown anddescribed, that the requisite pressure of the brush against the innersides of the bottle may be obtained in order to cleanse the bottlesperfectly and the bottles also readily adjusted or applied to themachine so that the operation of cleansing the bottles is performed withgreat facility and in a perfect manner.

To enable those skilled in the art to fully understand and construct myinvention, l will proceed to describe it.

A represents a horizontal bed, on one end of which a head B is secured,said head having a mandrel C fitted within it. The head B is stationaryand a pulley D is placed on the mandrel C, the mandrel being driven by abelt (a.) from a wheel D on the driving shaft E. To one end of themandrel C a rod or shaft F is attached. This rod or shaft is cylindricaland hollow for a certain distance, from (l) to (2) and the remainingportion is of semicylindrical form, or the rod or shaft may be describedas being divided longitudinally from its outer end to 1 rod or shaft Fthe pin (b) the point (2) the end of the cylindrical portion one half ofthe rod being removed. Within the cylindrical portion of the rod orshaft F a square or rectangular bar G is fitted and allowed to slidefreely therein. This bar is connected to a sliding collar H which isfitted on the tubular portion of the which connects the collar H withthe bar G being fitted in v slots (o) in the rod or shaft F. To the endY of the bar G a bar I is pivoted, and the bar I has bristles (d) fittedin it, to the end of the bar I a similar bar J is pivoted also providedwith bristles (d). The bar .I is @0nnected to the rod or shaft F by barsK, L, one end of which are pivoted to the bar J L and the opposite endsto the rod F. The

bar L is provided withY bristles. The outer part of the rod or shaft Fis slotted as shown at (e) Fig. 1so as to receive the bar K. The collarH is grooved and is fitted in the upper end of a vertical plate My whichis attached to a horizontal slide N on the bed A,

the slide being kept in proper position by' guide pins (f) which passthrough slots (g) in said slide. T

O is a lever which is pivoted to the bed A,

at (it). This lever is connected to the slide Y N at (z') and P is a,spiral spring, which is fitted in a slot (j) in the bed A. One end ofthis spring bears against a projection (7e) on the under side of theslide N.

Q, Q represent two guide rods which are' and fitted on the guide rods asshown, formsl a sliding or reciprocatinig holder for the bottles.

The operation is as follows: The bottles to be washed are placed in atank or reservoir of water placed near the attendant or operator, whograsps a bottle and fits it in the holder R the neck of the bottle beingfitted in the notch in the cross piece (m) and the body resting in thesemi-annular cross piece (m). rllhe bottles always contain some water asthey are immersed in the tank, a certain quant-ity of water will ofcourse escape from them when placed in the holder but enough 4willremain for cleansing purposes. The spring P in bearing against theprojection on the slide N keeps the collar H forced out from the head Band the bars I, J, are in contact with the rod or shaft F, as shown inFig. 2. When the operator has adjusted the bottle S in the holder, hemoves the holder in the direction indicated by arrow (l) and the brushbars I. J. and rod or shaft F pass into the bottle, and when they areinto the bottle the required distance the lever O is moved in thedirection indicated by arrow (2) and the collar H and bar G are moved ofcourse in the same direct-ion and the brush bars I, J will be forced outfrom the rod or shaft F and the brush bar L moves at right angles ornearly so with the rod or shaft. The brushes (el) therefore of the barsI. J. bear against the side of the bottle and the brushes (d) of the barL bear against its bottom as shown in Fig. l and a rotary mot-ion beinggiven the mandrel C. and rod or shaft F from the shaft E, the bottlewill be thoroughly cleansed by a few revolutions of said rod. Thebrushes may be made to bear with the requisite degree of pressureagainst the bottle by pressing against the lever O suficiently hard inthe direction of arrow 2. The mandrel C is not stopped but rotatescontinuously, the operator places the bottles one at a time in theholder forcing them up toward the brushes whichl pass into the bottle7and are then expanded by moving the lever O the bottles as they arecleaned being moved back and removed from the holder and fresh onesplaced in it.

I am aware that expanding brushes constituted similarly to the oneherein described have been previously used for the same purpose, butthey have been arranged in quite a complicated way so as to precludethem from general use, on account of the cost attending theirconstruction and keeping them in repair.

I do not claim separately or in itself considered, the expanding brush,for that or its equivalent has been previously used, but

Having thus described'my invention, what I claim as new and desire tosecure by Letters Patent ismr The expanding brush formed of the brushbars I, J, L connected to the rod F and bar Gr as shown and expanded andcontracted by the lever O and spring P, when said brush thus arrangedand operated is used in connection with the sliding holder R for thepurpose set forth.
